Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031678, here are decompositions:

157 + 1031521 = 1031678
199 + 1031479 = 1031678
331 + 1031347 = 1031678
379 + 1031299 = 1031678
397 + 1031281 = 1031678
541 + 1031137 = 1031678
631 + 1031047 = 1031678
691 + 1030987 = 1031678

Showing the first eight; more decompositions exist.
